A vineyard is a complex agro-ecosystem composed of a large number of organisms and at the heart of which is the vine. The functions and contributions of these organisms can vary from no influence to a major impact on vine. An organism can be desired (e.g. for soil protection, pest control) or unwanted (e.g. disease, pest). The molecules synthesised by vineyard organisms or by the vine itself in reaction to a stress can significantly impact the quality and chemical composition of the grape berries and the wine. In addition, the presence of unwanted organisms can lead to a change in the cultural practices which, in turn, influences the grape quality. In certain cases, the impact of the vineyard organisms remains quite mysterious and it is therefore difficult to understand the relation between the impact of a single or several organisms (e.g. soil microorganisms, indigenous yeasts, general biodiversity) and a distinctive feature of the final product.
The aim of this session is to present relevant recent research results on the direct or indirect impacts of vineyard organisms on the vine and the resulting wine.
